Against the backdrop of rapid development of information technology, teachers in higher education institutions are facing unprecedented opportunities and challenges in their professional growth. The application of information technology not only changes the teaching mode and the allocation of educational resources, but also puts forward new requirements for teachers' knowledge system and professional abilities. This article analyzes the characteristics of teacher professional development under the background of informatization, and explores the main problems faced by teachers in technology application, resource acquisition, and conceptual transformation. A series of support strategies have been proposed to address these issues, including strengthening technical training, building resource sharing platforms, and promoting changes in teaching concepts, aiming to provide substantial assistance for the professional development of teachers in higher education institutions.
